This is so hard

You can do it! And it's totally not hard if doe right. The main thing is calories in vs calories out [MFP will help you calculate your ideal caloric limits to what you wanna lose per week-ish]. The first few pounds are gonna go QUICK, but please remember it is mostly water weight and is not an indication of how it will go the entire time!

I'm slowly increasing the intensities of my workouts. Starting out with just WALKING more is a huge difference.

Also; Please remember that 500 calories of juice and 500 calories of soda is still 500 calories, even if juice is 'healthier'.

As newbies to MFP I suggest some reading of some posts that will help you on this journey.
